To all whom it may concern:

Be it known that I, CHARLES A.'IsLE1B, a citizen of the United States, residing at Maywood, in the county of Bergen and State of New Jersey, haveinvented certain new and useful Improvements in Ribbon Blocks, of which the following is a specification. a

This invention has for its objectgto improve the construction of ribbon blocks so as to produce a stronger, more durable, more perfectly finished and otherwise better block than those now in use without unduly increasing the cost thereof. Occasionally ribbon blocks are madeof wood or sheet metal, but more usually of pasteboard or other stiff paper material because of its superior cl1eapness' and lightness. But "when made of paper material experience has shown that for the sake of uniform facility and accuracy the steps in the manufacture must be the following, to wit; a cylinder of the paper material to form the body must be inserted at each end into the upstanding flange of a cap of said material with cementing substance, as glue, between the flange of each cap and the corresponding end of the cylinder to bind the caps and body together; this involves considerable facility in assembling the parts and results in a more finished article than if the caps were assembled with the body by the latter being made to receive their flanges, but the block then has this series defect that the first layers of ribbon wound on the block, representing more or less length according to the thinness or delicate texture of the ribbon, become creased by the edges of the cap flanges and as a general rule have to be discarded as Waste and unsalable, and besides the blocks do not present a finish at the ends and instead of being square-cut or angular all around are rounded and frequently quite irregular. Another fault with the mentioned type of block is that the flanges of the caps, which are pressed up from the disks in forming the caps, have a tendency to spring back to their original position (in the plane of the disk), and so when the flanges are glued onto the cylinder ends they do not always remain glued down all around, but at points stand out more or less.

My ribbon block is constructed of paper material, but so as to avoid these defects and so as in addition to have superior strength and durability especially the portion thereof constituting its cylinder or In the accompanying" drawing, Fig. 1 is a side ribbon block, I

Fig. 2 is an end view; I Fig. 3 a section on line 3-3, Fig. 1;" 1 Fig. 4 a side elevation with parts broken Fig. 5' a side elevation b";and I Fig. 6 a side elevation of part b. My block includes, with'the two caps a of stifl paper material forming the ends of the block, a twoewalled body of stiff paper material, such two walls being indicated by thereference-character b 'b These two walls are concentric, the cylinders to form. them differing in diameter only by as much as the thickness of the material of the caps. The caps and cylindrical walls are united by layers of glue 0 or other cement. The caps are preferably so assembled with the walls, which have their ends cut 011' true to a plane perpendicular to the axis of each cylindrical wall, that the outer wall at least affords at each end edge the circumferential end angle of the block, which is therefore square-cut all around and in any event presents a finished appearance; in other words, each end of the cylinder extends at least as far as the outer surface of the cap.

The assembly of the parts may be accomelevation of the improved of parts-a a and plished in any Way so as to bring them into substantially the relation best shown by Fig. 4, having previously to the assembling applied glue or other cement to the parts so that the ends of the two cylindrical walls and the cap flanges will be left adhering or bound together. v

This ribbon block is very much strengthened because of the double-wall formation of its cylindrical part or body and because the material of the block is three-ply at its ends and the flanges of the caps are held by the outer cylinder in close contact all around with the inner cylinder and the cement sets with the parts confined in this relation. Its appearance represents a considerable im provement over the ordinary ribbon block because it is plain-cylindrical from end to end and because the ends of the block are square-cut; and in respect to its appearance noespecial skill in forming the block is required. Whatever trifling additional expense is entailed by the inclusion of two cylindrical walls instead :of zone wery materially ofiset by the saving of several ya rds of ribbon to each block because the improved block presents no circumferential *shotflders to form creases in the first wrappings of ribbon on the block.

While I have herein described the flanges of the caps as cemented to both cylindrical wallsil doaiotwish it'vt'o' be amderstood-that this is indispensable. 7 While it vis Zbest to cement all these parts together, if they 31118 held together in some other way, ;as by s'snugly fitting each eother, the cementing might be omitted; thus the caps need not necessarily be cemented to the inner cylinder, or, if the :outer oyilinder guite snugly fits the cap flanges, zcementem-igght be omitted between themk Havingthustfiully described my invention, what I claim and desire to secure by Letters Patent is: I I

A ribbon block comprising two cylinedrical walls =each formed aof :stifi paper =m-a- -YteriaI and forming thebodyiof the-block and :arranged one w'ithin andconcentric avithvand :spaced from the other and two caps each formed of :s'tifl? paper material (and diorming =the ends of the block and reach (having its flange lying ,and held between the two corresplnnding end portions lot the cylindrical wa s.
